A dielectric barrier discharge (DBD) reactor, driven by a pulsed corona surface discharge (PCSD), was developed for the removal of particulate matter (PM) in an undiluted exhaust gas of a diesel engine. The DBD reactor consisted mainly of alumina (Al 2 O 3 ) plates and metal meshes covered on the surfaces of Al 2 O 3 plates. The PCSD was carried out with a pulse power supply at atmospheric pressure and the temperature of exhaust gases. The energy efficiency for PM removal was 26.5 μg/J at maximum and 1 μg/J with 42% PM removal. The construction of the DBD reactor that promoted PM deposition on Al 2 O 3 surfaces improved energy efficiency. The constants in PM removal model were given. © 2004 American Institute of Chemical Engineers AIChE J, 50: 1901–1907, 2004
